I'm not familiar with Dell Linux software, but sure, you should certainly be able to see the status of all drives as well as any RAID arrays. You should also be able to configure notifications, perform manual expansions and rebuilds etc.
As I said, I don't know the specifics when it comes to Dell server hardware (such as what they actually call their management software), but hopefully the software is already installed. If it isn't, then (somebody hasn't been doing his/her job, and) you should be able to find what you need here
. RHEL is supported, so you should be able to run software for the equivalent RHEL version on CentOS.
